Hassan II Mosque belongs to the Common Era — dated here to c. 1993 CE at Casablanca, Morocco. Dates mark a scholarly centre of gravity (dedication, completion, or iconic phase), not a single foundation day.

A minaret 210 metres tall and a prayer hall with a retractable roof over the Atlantic.

How it amazes the brain

Built partly on the ocean, with glass floors over sea in places — craftsmanship from across Morocco.

Why it counts as a wonder

It never needed a contest ballot to scramble the brain: scale, craft, or sheer improbability is enough.

A wonder that lets waves under the faithful.

On dating

CE means years after the traditional birth of Christ. A monument listed as c. 1993 CE may have been founded earlier, rebuilt later, or become famous only in one phase. Engineering wonders (dams, tunnels, orbiting labs) are dated to opening or assembly.

This is story 92 of 100 in The Trend Ledger’s illustrated desk on world wonders raised after the birth of Christ — the companions to our BCE series.
